What is the meaning of i+=2 in C programming language?
- It is the same as i=i+2;
- It makes the code a little bit shorter. No effect on execution time.
C program to find area of square using default argument
#include <stdio.h>
using namespace std;
int squareD(int i=8,int l=7)//we have two default argument
{
return (i*i);
};
int main()
{ int result;
printf("Program for area of square using default argument");
result=squareD(5);// here 5 is argument that we have pass
printf("\nThe square is");
printf("\n%d",result);
result=squareD();// here we have not pass anything[ Default argument]
printf("\nThe square is");
printf("\n%d",result);// We have not used the value of L
return 0;
}
Output:
Program for area of square using default argument The square is 25 The square is 64
